However, when I can't seem to connect it to the computer. It says "Accessport not connected" even though the AP turns on. I've tried this on the latest version of the AP Manager on both OSX and Vista.

Also, I've tried connecting it to the car but it says that the car's ROM was unidentified and I should contact technical support. From the "user tools", I was download the car's ECU information into the AP but this seems useless if I can't connect it to a computer!
